Grain-elevator



UNITED STATES Application filed March 2, 1880.

To all whom it may concern:

Be it known that I, WILLIAM W. SToLL, of Brooklyn, New York, haveinvented a new and useful Improvement in Elevators, for which, with myknowledge and consent, a patent has been obtained in Great Britain, N o.414, bearing date January 31, 1878, and issued to William Henry Power,of London, and of which the following is a specification.

This invention relates to that class of grainconveyers employing anelevator-trunk capable of being adjusted vertically and outwardly; andthe invention consists in a novel combination and arrangement of parts,which will be fully hereinafter described, and pointed outin the claim.

The accompanying drawing represents a side view, partly in section, ofmy improved elevator as placed on a vessel or float.

A is the elevator-trunk; a, the elevator-shaft; B B, the two side piecesof the swinging arm or yoke; G, a vertically-adjustable sliding frame,to which the inner end of the swinging arm is attached or pivoted, andwhich slides between the vertical guides K K. D is the spout of theelevator discharging the grain.

The elevator A is of the usual construction. The swinging arm consistsof two side pieces, B B. Near the forward end are the bearings for theelevator-shaft a, with the pulley o. The inner'end of the swinging armis hinged to a shaft, c, having its bearings attached to the outer endor face of the sliding frame 0. On

this shaft e are fixed the pulleys f and g, which latter communicatesmotion to the elevator- PATENT OFF CE.

shaft to by means of a belt, cl. The shaft 0 is revolved by means of anendless belt or rope, u, from the driving-pulley m, passing over thepulley f, which is fixed on the shaft. This belt also passes over theguide-pulleys k and lon the inner face of the sliding frame and over theguide-pulley n, which, like the driving pulley, has its bearings on thefixed framework. This arrangement of pulleys admits of vertical motionof the sliding frame O.

The hoisting apparatus H has two drums, oneof which serves to raise orlower the sliding frame 0 by means of a rope passing over the block 1",while the other one serves to adjust the position of the outer end ofthe swinging arm by a rope passing over the blocks 0 and 1).

What I claim is- In an elevator, the combination of a frameworkconstructed with vertical grooved guideways K, the sliding frame 0,arranged in such guide-grooves, the outwardly-extending arms B, hingedto said sliding frame and provided with pulleys for driving theelevator-buckets in the trunk A, which latter is pivoted to the outerends of the arms B, and the hoisting mechanism having threewinding-drums and independent ropes or bands passing up over pulleys,and connected, respectively, with the elevator-trunk, the swinging arms,and the sliding frame, all as and for the purpose described.
